Lowering costs and increasing margins is the game of the business everywhere, east or west. It is largely the policies of Chinese government that made manufacturing in China especially lucrative, even considering the bad business culture.
Sure, but there is no free lunch. You're getting cheaper stuff but for that you're sacrificing your local industry and the environment by offshoring the environmental damage to places with less environmental protection laws. There is no free lunch. The right way to lower cost is by pursuing automation, not by offshoring the environmental damage and using sweatshop workers in areas with human rights violations.
I would say Western governments did a poor jobs protecting their countries from unfair competition from China, but also the practices are indeed unfair, I can't agree Chinese government is not to blame.
Such as USA with $11B of goods manufactured by forced labour in prison camps?
(Note: this is not whataboutism, it’s pointing out hypocrisy.)
